ANNEX 2 ANNEX II OCCURRENCES RELATED TO TECHNICAL CONDITIONS, MAINTENANCE AND REPAIR OF
THE AIRCRAFT
1. MANUFACTURING
Products, parts or appliances released from the production organisation with deviations
from applicable design data that could lead to a potential unsafe condition as identified
with the holder of the typecertificate or design approval.
2. DESIGN
Any failure, malfunction, defect or other occurrence related to a product, part, or appliance
which has resulted in or may result in an unsafe condition.
Remark: This list is applicable to occurrences occurring on a product, part, or appliance
covered by the type certificate, restricted typecertificate, supplemental typecertificate,
UKTSO authorisation, major repair design approval or any other relevant approval
deemed to have been issued under Commission Regulation (EU) No 748/2012.
3. MAINTENANCE AND CONTINUING AIRWORTHINESS MANAGEMENT
(1) Serious structural damage (for example: cracks, permanent deformation,
delamination, debonding, burning, excessive wear, or corrosion) found during
maintenance of the aircraft or component.
(2) Serious leakage or contamination of fluids (for example: hydraulic, fuel, oil, gas or
other fluids).
(3) Failure or malfunction of any part of an engine or powerplant and/or transmission
resulting in any one or more of the following:
(a) non-containment of components/debris;
(b) failure of the engine mount structure.
(4) Damage, failure or defect of propeller, which could lead to in-flight separation of the
propeller or any major portion of the propeller and/or malfunctions of the propeller
control.
(5) Damage, failure or defect of main rotor gearbox/attachment, which could lead to in-
flight separation of the rotor assembly and/or malfunctions of the rotor control.
(6) Significant malfunction of a safety-critical system or equipment including
emergency system or equipment during maintenance testing or failure to activate
these systems after maintenance.
(7) Incorrect assembly or installation of components of the aircraft found during an
inspection or test procedure not intended for that specific purpose.
(8) Wrong assessment of a serious defect, or serious non-compliance with MEL and
Technical logbook procedures.
(9) Serious damage to Electrical Wiring Interconnection System (EWIS).
(10) Any defect in a life-controlled critical part causing retirement before completion of its
full life.
(11) The use of products, components or materials, from unknown, suspect origin, or
unserviceable critical components.
(12) Misleading, incorrect or insufficient applicable maintenance data or procedures that
could lead to significant maintenance errors, including language issue.
(13) Incorrect control or application of aircraft maintenance limitations or scheduled
maintenance.
(14) Releasing an aircraft to service from maintenance in case of any non-compliance
which endangers the flight safety.
(15) Serious damage caused to an aircraft during maintenance activities due to incorrect
maintenance or use of inappropriate or unserviceable ground support equipment
that requires additional maintenance actions.
(16) Identified burning, melting, smoke, arcing, overheating or fire occurrences.
(17) Any occurrence where the human performance, including fatigue of personnel, has
directly contributed to or could have contributed to an accident or a serious incident.
(18) Significant malfunction, reliability issue, or recurrent recording quality issue affecting
a flight recorder system (such as a flight data recorder system, a data link recording
system or a cockpit voice recorder system) or lack of information needed to ensure
the serviceability of a flight recorder system.
ANNEX 3 ANNEX III OCCURRENCES RELATED TO AIR NAVIGATION SERVICES AND FACILITIES
Remark: This Annex is structured in such a way that the pertinent occurrences are linked with
categories of activities during which they are normally observed, according to experience, in order to
facilitate the reporting of those occurrences. However, this presentation must not be understood as
meaning that occurrences must not be reported in case they take place outside the category of
activities to which they are linked in the list.
1. AIRCRAFT-RELATED OCCURRENCES
(1) A collision or a near collision on the ground or in the air, between an aircraft and
another aircraft, terrain or obstacle¹, including near-controlled flight into terrain (near
